1. A Super-Regional Modeling Testbed for Improving Forecasts of Environmental Processes for the U.S. Atlantic and Gulf of Mexico Coasts Don Wright, SURA Principal Investigator Rich Signell, USGS Technical Advisory and Evaluation Group Chair

2. Motivation for the testbed: improving prediction of environmental processes Design of this testbed Year 1 products Future work Outline

3. IOOS Budget add-on (FY10) “$4,000,000 is for a competitive extramural regional test bed… to understand, predict, and mitigate the consequences of both extreme events and chronic conditions in the U.S. Atlantic and Gulf regions. Such a test bed should include no less than 20 academic partners and research institutions to guarantee it is multi-disciplinary and inclusive of community-modeling”

4. Improving Forecasts of Coastal Environmental Processes Factors: open boundary conditions, surface and river forcing conditions, enhanced physics, adjustable parameters, data assimilation, numerics, amount of data assimilated, skill of modelers(!), vertical and horizontal resolution, coupling to wave and met models. “Which model is better?” is not the right question. What factors in the simulation resulted in a better solution? How much better? At what cost?

5. Defining Improvement To measure improvement for environmental processes, we need to define skill metrics for specific environmental processes and often for specific region Inundation, search and rescue, deep oil spills, navigation, hypoxia, harmful algal blooms, diver operations, alternative energy siting, beach erosion, regional impact of climate change all require different skill metrics Operational centers need community help in this process – too broad for the Federal Backbone!

6. The ocean community needs a common cyberinfrastructure to access, analyze and display data from the different models: each model currently has their own standards and toolsets A Common Cyberinfrastructure for Model Data Structured Grids Unstructured Grid 5x5 6x3 10 nodes Variety of Stretched Vertical Coordinates

7. Build a common infrastructure to enable access, analysis and visualization of all coastal ocean model data produced by Federal Backbone & RAs Develop skill metrics and assess models in three different regions and dynamical regimes, to ensure a robust and powerful infrastructure Identify factors for transition to operations Build stronger relationships between academia and operational centers through collaboration A Testbed Framework for Coastal Ocean Models
